1. Renovate Existing Spaces

One of the easiest ways to add an extra room to a small home is by modifying or completing existing spaces like basements, garages, and attics. These spaces are perfect to convert if you’re looking at adding a guest room, building a family room or adding a home gym

Since you already have the basic structure, adding to your living space will only take some insulation, plumbing, and electrical work, with some amount of fabrication depending on how much natural light you want to let in.

Remodeling basements, garages, and attics are all unique in their way, though. For example, while natural light and ventilation can be a problem in all three cases, sliding and/or dormer windows can be easily added to attics and garages. Basements will predominantly need artificial lighting.

Insulation against the elements is something you will have to spend on in all three cases. For example, most attics will have roof vents that will need to be addressed if it is to be converted into a living space. A new staircase may also be in order. You will also have to see if your existing HVAC system can support your new living space.

On the other hand, converting a garage into a living space may need you to raise the height of the flooring and the ceiling, change the door to better suit the new purpose, add new heating, plumbing, new windows and maybe even a carpet for the floor to complete the project.

2. Add A Sunroom

A great way to increase the square feet of your living room while adding to the curb appeal of your home is to build out and add a sunroom.

Since sunrooms are predominantly windows, they allow in oodles of natural light and make for great cross ventilation. Sunrooms are also amazingly affordable and customizable. The market has great do-it-yourself kits made by multiple manufacturers, giving you options in design while guaranteeing you savings because you don’t need to hire a contractor.

You could even make building your new sunroom a family activity, allowing you to spend some quality time together.

3. Build Up

If you’re looking at building yourself a master bedroom and master bathroom, you’ll need considerably more space. You might have to consider adding a new story to your home, or building up, as it’s often called. 

Building up will mean drawing new floor plans, and will give you the freedom to choose how large you want your living space to be, what you want it to look like, what kind of flooring and fittings you want, etc.

Building up would also allow you to add private luxuries such as walk-in wardrobes, private outdoor decks with access from your master bedroom, his and her wash closets, jacuzzis and/or large bathtubs, etc.

4. Build Above Your Garage

Another easy way to add square footage if you’re looking at building your kids a room or adding a guest room is to build on top of your garage. If your garage is already flat-roofed, you can save money on the flooring by reinforcing the roof and adding the kind of tiles, wood or carpet you want. 

You could consider reducing costs by incorporating large windows and aluminum sliding doors, which are also efficient in letting in natural light. 

You will, however, need to work closely with your plumber and your contractor to make sure your pipes are laid only overheated areas and not in external walls. It would also help to keep in mind that you will need modifications to your existing home to be able to access the new part of the home.

5. Easy To Build Mudrooms

If you live in a four-season area and need to build a mudroom, you could do so with relative ease by enclosing a part of your porch. You could also increase the amount of natural light your existing living area gets by adding large windows to the new mudroom.
